Closest i'd use would be Pedal Enclosures some nice angled enclosures http://www.pedalenclosures.com/Products ... fault.aspx not the same but, they have a retro charm (Plus for a Gary Hurst Tone Bender there Prism Enclosures would be perfect)

Having a bit of a nightmare with this Supa Fuzz build,that was ment to be a gift for about 3 weeks ago so think its time for a little help!

Im using 3 Philips OC75, and have wired them up though the breadboard with matching color to the diagram below (RED= E Yellow=B Green=C)  and am going by the Collector being indicated by the red dot on OC75.

Anyone spot anything glaringly obvious, or have suggestions?   

oh, and I should say I get the bypass signal no problem but nothing when the effects on.

Flip your battery wires. You got it set for negative ground, it needs to be positive. It should work like a charm once you do that.

The diagrams should be changed too to avoid further confusion.

Might be slightly off topic, but has anyone ever seen a Marshall Fuzz-Reverb unit? I have a schematic at home for one that was sent to me years ago and it's just a Supa Fuzz with a transistorized spring reverb unit after it.

Switch polarity and it worked for about 5 minuets, though the attack pot did nothing, and now its all stoped working :whappen:

Post pictures of your wiring again. Sounds like your groundings still off since the attack knob didn't work.
